Other objects and advantageswill be apparent fromtheV following description when takenV in connection with the accompanying drawing.

In the drawing:

Figure 1 is a plan view of the invention,

certain ofthe parts being broken away, and made in accordance with the Vpresent invention.

Figure 2 is a fragmentary plan view of the device, with certain of the parts removed to disclose parts otherwise hidden.

Figure 8 is a rear elevationlof the device.

Figure 4 is a detail sectional view on the line 4-4- of Figure 1.

Referring particularly to the accompanying drawing, 10 represents a suitablekframe which is secured to a plowl at one end. Pivotally connected to the intermediate portion of the frame, and extending laterally from opposite sides thereof, are the draft beams 11 and.12.`v Pivotally securedV to the frame 10, adjacent the rear end, and at one side thereof, as shown at 13, is a pair of parallel links 14, said links extending obliquely and longitudinally of the frame, and having the short links 15 plvotally con'- carried by the frame 10, receives vthe adjacent link 14 slidably therethrough, and maintains said link in close relation to theframe.

The other ends -of the short links 15 are pivotally connected to the kopposite sides of the angle portion of an angle lever .17. Se-

cured to the opposite faces of the forward wardly projecting `vends of said plates is theY inner end of a short link19. .Pivotally connected to the frame 10, inwardly of the A guide 16,V

das is; is@ linkL iid-.which extends forwardly and laterally from the frame, and

has in its outer end, a longitudinal slot 21. This slotted end of the link 2O is pivotally and slidably connected to the youter end of the adjacent *armv of the angle lever 17, by means ofthe pivot member 22, disposed through said arm and the slot 21. Pivotally connected tothe pivot Vmember 22, at one end, and-pivotally connected to the forward4 end of the linkV 19, at its other end, is a ylink 23. Pivot-ally carried bythe beamr 11, adjacent its inner end, are the forwardly ex- .tending parallel links 24, and disposed through the forward ends of the links is the before-mentioned pivot member 22, the

adjacent ends of the links 20 and 23 being Y Vdisposed between said links 24.

Two horses are adapted to be hitched to` each of the draft beams 11 and 12, and as the horses of the beam 12 pull a degree stronger than those of the beam 11, the links n cause the lever 17 to be rocked, and its lateral arm carrying the pivot member 22 to push rearwardly on the linksl 24, .and

rswing the beamll rearwardly, thus holding back the horses of the beam 11, with the result that the latter horses will have no greater leverage, than the other horses, thus .Y

equalizing the pull on .bothbeams` ThusA the horses on the unplowed land cannot overbalance the pull vofv the horsesin the plowed land, but produce `an equalized draft on both-sides of the device, with vthe result that the plow will not be pulled fto greater extent toward one side than toward the other. Y e

VAdditional beams 12 are Vpivotally connected to thefront of the frame12, and have i their outer ends connected to the correspondn ing ends of the links .or beams 12,' by means'V of the link 10f, whereby said rbeams 12 and- 12 will maintain-their parallel relation,.

during their pivotal movements.

lVhile vI have shown a form of the device'y which is adapted for'use with a four horseV team, I wish itunderstood that,l five horses `may be hitched to vthe' device, by connectingj three of thehorses to the lever or beam 'on i rplowed land; side. The present devicer is capable of use inl ri.frais:fr.;amer.

connection with right or left hand plows, sulky ploWs, or asa three horse evener inv connection With a. eultivat'or.

lVhat is Claimed is: Y.

A draft equalizer including a support, op# positely extending draft beams carried byi the support, an angle member on the support, links connecting the angle portionof the angle member With one end of the sup- 10 port, a link connected With one end of the angle member and to one of said beams, links' pvotally carried by the support and pivotally connected with one end of the angle. member, one of said links beingslicb ably connected Vwith said angle member, and links lcarried by the other beam and pivotally connected with the other end of the angle member.

In testimony whereof, I affix my signature.
